A team at Britain's Wellcome Trust Sanger Institute is developing a new catalogue of so-called "loss-of-function" LoF gene variants to help identify new disease-causing mutations, and say their work will help scientists better understand the normal function of human genes.

That said, many small duplications do not show much effect because the amount of gene product is regulated to produce homeostatic levels also why most loss-of-function mutations are recessive.

As the workers note: Heterozygosity for partial or complete loss-of-function alleles . . . may have little negative effect on overall fitness including transmission of mutant alleles, while providing a modest but significant protective effect against malaria.

Just like in model organisms, identifying the phenotypic consequences of loss-of-function mutations gives a somewhat clearer picture of what processess that gene is involved in.

Hemophilia A is defined by loss-of-function mutations in factor VIII, and there are greater than 40,000 registered patients in the U.S. and E.U. Hemophilia B, defined by loss-of-function mutations in factor IX, affects greater than 9,500 registered patients in the U.S. and E.U. Standard treatment for hemophilia patients involves replacement of the missing clotting factor either as prophylaxis or on-demand therapy.
